Robbie Williams has revealed how becoming a father has opened his eyes to the dangers in the world for children, as he joins forces with David Beckham for UNICEF’s Children in Danger campaign .

The Angels singer has recalled his heartbreaking visits to locations that have been ripped apart by disasters or poverty, touching on his visit to Haiti in 2010 as well as his trip to Mexico City in 2012 for Soccer Aid.

The former Take That star visited Haiti after the devastating earthquake hit in 2010, which killed nearly 250,000 people and left a million people homeless.

“This trip really opened my eyes to some of the conditions children around the world have to live in. So many kids in Haiti had lost everything – their homes, their families and even their lives,” the 40-year-old said.

“Whilst I was there I met a tiny baby called Mary Michelle, born on the day of the earthquake, who was only alive thanks to the food and support Unicef had given her grandmother after both her parents were tragically killed. There are millions of children, just like Mary Michelle, whose lives are in danger and since becoming a dad it’s made me even more aware of how important it is to do something to help.”

Two years ago, in the same year that Robbie’s daughter Teddy was born, Robbie went to Mexico City where he witnessed how vulnerable the children were. He said the conditions were “absolutely shocking” in the slums that he saw.

“I will always remember the kids I met on that trip. Young children like Angel and his little sister who were at risk each day of being snatched by criminal gangs whilst their parents struggled to make a living to feed their family,” he said.

“The slums I visited felt so unsafe and it was clear that the children faced a number of threats everyday such as violence and abuse. Seeing all this really hammered home how dangerous the world can be for a child and was all the more overwhelming knowing that we had a little one in Ayda’s tummy. “

Robbie also added: “The experiences I’ve had with Unicef have been incredible and above all have made me realise how lucky I am and how lucky my own children are to be safe and protected.”

Longstanding Unicef Ambassadors Robbie and David Beckham have joined the Children in Danger: to End Violence against Children campaign.

In a set of striking photos, the pair hold a hand out as a gesture to highlight the campaign to protect children from violence, disease, hunger and the chaos of war and disaster.

Unicef Goodwill Ambassador David Beckham said: “If you saw a child in danger, any child you would instantly step up and protect that child from whatever threat they were facing. Millions of children around the world are facing dangers every day - violence, disease and disasters.

"We need to grab this opportunity to step up and protect them now. Join me in supporting Unicef’s Children in Danger campaign and we can all help keep these children safe.”about this new information and are reassessing the future of the series.”
